Summary
The prevalence of atopic dermatitis (AD) in Finnish adults is high, affecting over 20% lifetime and 10% in the past year. AD burden extends beyond childhood, impacting the growing adult population.
Area of Science:
- Dermatology
- Epidemiology
- Public Health
Background:
- Atopic dermatitis (AD) prevalence is rising globally.
- Limited research exists on AD in adult and elderly populations.
- Understanding adult AD epidemiology is crucial for public health initiatives.
Observation:
- A national health examination survey in Finland assessed adult AD prevalence (≥30 years).
- Factors analyzed included living environment, socioeconomic status, lifestyle, and vitamin D.
- Both 12-month and lifetime AD prevalences were determined.
Findings:
- Lifetime AD prevalence was 21.9%, with 10.1% experiencing it in the past year.
- Highest prevalence observed in the 30-39 age group, decreasing with age.
- Parental education, younger age, ex-smoking status, female sex, and daily smoking were associated with active AD.
Implications:
- Finnish adult AD prevalence is among the highest reported globally.
- The aging population suggests a growing burden of AD beyond childhood.
- Further research into risk factors and management strategies for adult AD is warranted.

3.3K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
